Title: Optical type mechanical quantity measuring apparatus
Inventor: OGITA EIJI
IPC: G01B11/00
Filed: 1982-06-25
Abstract: PURPOSE:To measure the three-dimensional mechanical quantity by causing an interference between a speckle pattern formed with a mobile diffusion surface and a reference light from a fixed reflection surface. CONSTITUTION:Light from a light source 1 irradiates a target 4 passing through a first polarized beam splitter 21. The light reflected from the target 4 enters a light receiver 7 reflected with the first PBS21. The light which enters the first PBS21 from the light source 1 and passes through first and second PBSs 21 and 22 reflected with a mirror 6 enters a light receiver 7 as reference light. A speckle pattern is formed on the light receiver 7 in such a manner as to be overlapped by a Michelson interference fringe. The three-dimensional mechanical quantity is measured from the movement of the speckle pattern and the movement of the interference fringe.
